Hugo Güldner designed what is believed to be the first operational two-stroke diesel engine in 1899, and he convinced MAN, Krupp and Diesel to fund building this engine with ℳ 10,000 each. [2] Güldner's engine had a 175 mm work cylinder, and a 185 mm scavenging cylinder; both had a stroke of 210 mm.

The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil . Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes , and produces 80.08 megawatts .
The engines operates on the 2-stroke cycle principle, are air started, and are rated at 1600 bhp at 756 rpm on the 16-248 and 750 rpm on the 16-278A. The size of the bore and stroke of the 16-248 engine is 8 + 1 ⁄ 2 inches and 10 + 1 ⁄ 2 inches respectively as compared to 8 + 3 ⁄ 4 inches and 10 + 1 ⁄ 2 inches for Model 16-278A.
Hot-bulb engine (two-stroke). 1. Hot bulb. 2. Cylinder. 3. Piston. 4. Crankcase Old Swedish hot-bulb engine in action. The hot-bulb engine, also known as a semi-diesel [1] or Akroyd engine, is a type of internal combustion engine in which fuel ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb ...
In the mid-1920s Sulzer started to advertise their airless Diesel engines, meaning they were using liquid injection rather than injecting the fuel using an air-blast (as used by Rudolph Diesel). They exhibited their 300hp 2-stroke airless engine, suitable for yachts, tugs, barges, etc at the Olympia Shipping Exhibition of 1925. [13]
Diesel engines have the lowest specific fuel consumption of any large internal combustion engine employing a single cycle, 0.26 lb/hp·h (0.16 kg/kWh) for very large marine engines (combined cycle power plants are more efficient, but employ two engines rather than one).
Uniflow diesel engine, a two-stroke diesel engine with inlet through piston-ported fixed ports in the lower part of the cylinder, and exhaust through valves in the cylinder head. Opposed-piston diesel engines, where two cylinders share opposite ends of the same cylinder. These use piston-controlled ports for both inlet and exhaust.
